Is C# with XNA Good?

16 November 2012 - 10:00 PM

Hello all. I have been doing programming for a while and was thinking of trying out C# with XNA for making games. So far I've been doing all my work with Java and I was wondering if there are any advantages to making the switch to C#. I keep hearing a lot of good things about C# and XNA, but is it any easier to get things done with that than in Java? For me my main problem is working with graphics as I'm not a good artist and I don't really know how to make art. So far I've been limited to what I can draw with basic shapes. If I was to stick to Java could someone give me a recommendation on how to make a decent 2D game with more than basic art? Thanks

Enemy only shoots once. Help

17 October 2012 - 09:50 PM

Ok so my problem is in my game I have two enemies. One of them is human controlled and can shoot at will. The AI however, seems to be a little broken. In my shoot method in this class, which is the enemy class, I try to use the system for shooting that I used for the player and I call the shoot method in run so it continuously updates. I can get one shot off right at the beginning, but I can't shoot any more after that. I've tried everything I know...and now I'm basically stuck. I want to see if I can do more with this game but for weeks I've struggled to no avail trying to figure this out. Help please? It would be very appreciated. I can include the other classes if needed just ask. So maybe you can run the game to see what I mean.

Java Collision Detection Help

25 July 2012 - 08:24 PM

I copied the code from Eclipse because the adding it seemed to cut it off after 60 lines. I can fix it if you tell me how and you want it in the special box. Anyways this is the enemy class in my game. Currently what I have is a little tank that moves and shoots bullets at an enemy(moving square). When he shoots the enemy health decreases, it reverses the enemy direction and the score goes up by 100. My problem is basically that the collision detection seems to be random...Sometimes it will count the bullet as 1 hit...sometimes 2 or 3. I don't know why it's doing this. Can anyone help or give suggestions? All help appreciated. Thank you.
